SPECIFICATION forming part of Letters vPatent No. 230,586, dated July 27, 1880.

Application filed May 15, 1880.

To all whom it may concern:

Be it known that I, CHARLES M. SToUP, of Flat Bock, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in -Thill-Couplings, of which the following is a speciiication.

The nature of my invention relates to an improvement in thill-couplings of that class wherein a latch bolt or spindle is impelled through the bolt-holes of the thill-clip by a spiral spring 5 and it consists in the novel and peculiar construction and combination of the elongated thill bolt with a bracket on the quarter-clip, its actuating-spring, and an inclosing-case for the same, as more fully hereinafter set forth.

Figure l is a perspective view. Fig. 2 is a longitudinal section.

In the drawings,A represents the axle-arm, with the usual thill-elip et and quarter-clip b, the latter having a bracket, b', forged on the front end of its bar, with an eye in the axial line of the'bolt-holes in the thll-clip.

B is the rear end of the thill, with the iron thill-hook B', behind which a rubber block or anti-rattler of vulcanized rubber, a', is inserted between the jaws of the thill-clip.

C is an elongated bolt playing through the (No model.)

eyes of the clips c and b. It is formed with ,three shoulders, c c c2. The shoulder c2 serves as a stop to limit its movement forward in the thill-clip. The shoulder c serves as a gripe by which it may be retracted, and between the shoulder c and the bracket b of the quarterclip a spiral spring, d, is interposed to automatically project the outer end through the eyes of the thill-elip.

The spring is covered and protected by a cylindrical casing, c, extending outwardly far enough to conceal it and the shoulder c.

By this construction and arrangement it is impossible for the thill-bolt vto become detached and lost, while for ease and facility of operation it cannot be excelled.

What I claim as my invention is- In combination with the thill-clip a and quarter-clip b, with its bracket b', constructed as described, thecQupling-boltC, provided with shoulders c c c2, actuated by the spring rl in its case e, and playing through the eyes of said clips, substantially as described and shown.
